To all whom it mag concern.-

, Be it known that I, Isaac KARPEN a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Mattresses, Cushions, &c., of which the following is a specification.

My invention relates particularly to theupholstery of mattresses, cushions, couches, sofa-beds, &c.

My primary object is to provide for a more compact arrangement of sp s than has "heretofore beenknown and to Improve the construction in other respects economy of construction being also a consideration.

The invention is illustrated in the accompanying drawings, in which- Fi e 1 represe ts a .a cus 'on or mattress constructed in accordance with my invention; Fig. 2, a broken plan view of a flexible spring-casi in'one sta e of development of the same; ig. 3, a bro en perspective view of the same in another stage of development; Fig. 4, a broken perspective view of the same in another stage of development; Fig. 5, a sectional view illustrating the grouping ofthe spring .pockets or receptacles during the insertion of, the springs, and Fig. 6 a similar section showing the grouping after completion of a row of springs.

The mattress,

preferred construction composed of a series ,of

s ring-casings f and s uarehelical springs inclosed in the podkets of each casing.

. Each casing is of cloth fabricsuch as duck,

canvas, cheese-cloth, or the like-and .is

. formed with a series of alined pockets or inof the pockets.

the outlines of dividual receptacles for the several springs of each row. The .several casings are arranged. in close parallel relation with the springs on end and are joined together by any suitable means, as by stitching.

Each casing f preferably comprises two strips of fabric f 2 f of uniform width laid one u on the other, with one lateral border of eac strip forming a rojection or flap f. The stri s are joined h parallel rows of stitches j f 8 f f mar 'ng the separation he stitches preferably stop short of the overlappi edges of the strips. In Fig. 3 the folding of t e fabrics to produce pockets of square cross-section and the fo ding of the flaps to enable broken plan view of cushion, or the like is iii the the s rings.

them to be foldedioverto form the endsof the pockets is illustrated, and in Fig. 4 one of the flaps is shownfoldedover and partially sewed in place. By preference one of the fla s is sewed toclose the pockets at one end be ore the s rings are inserted, and after the insertion o the springs the other flap is sewed on a s ecial machine to close the pockfolding the fabric to form-the open-ended box-form envelops or etsat the ot or end.

In the operation of receptacles for the springs the stitc having the oddly-indexed c aracters mar 'corners of the envelops at the lower side of the casing, and the stitchings having the evenlyindei red characters mark corners of the envelo s at the upper side of the casing, the stitchings being1 at diagonally ogposite lateral corners of t e receptacles. Fig. 2 the points on the flap and receptacles which are rought together when the flap is folded to the sewing position are indicated by the characters a b c d e, the points having the same letter being brought together. In Fig. 3 the corners at the near ends of the rece tacles not previously marked are indicate by the characters 9 g g g The upwardlydrawn folds of the flap fare designated h,

and it will be observed t at one side or partition-wall of each receptacle is formed b extending this fold across the casing, a the opposite sides or partition-walls of the re-' cc tacles are formed by downwardly-drawn f0 ds h. After the folds are com leted, as shown in Fig. 4, the edges are joine together by stitching k, a portion of which only is shown.

It will be understood that after the stitching is completed the rece 0 together and maintaine in the condItIon shown in Fig. 6, it bein understood that the o eration of sewin t e, remaining flap is slmilar to that alrea y described, except that the sewing is effected after the insertion of The final operation is performe on a sewing-machine having a table de ressed the thickness of the springs to enablh the edges of the fabric to be readily joined. When the casings with the springs mclosed are assembled and joined together,

as shown in Fig. 1, a com act arrangement .a bed spring or thorough uniformoutitssurface. It

tacles will be tied stn'ps. of fabric j oined by parallel, transverse.

connects casings, each casin having a sewill be understood that any suitablep'ad or cover may be applied to the mattress or cushion;

What Inegard as-new, and desire-to semn'e- 5 by Letters Patent, is

1. A spring-bottom of the character set forth comprising parallel rows of casings withspring-poekets of angular shape formed;

therein, and helical springs of angular form inclosed in said pockets.

2.4 A. spring-bottom of the character set forth com parallel casings Iiavin pockets of rectangular form, and lichen. springs of'rect in form inclosed in said pockets, each caslng comprising overlapping rows 0!? stitchings and formed into rectan Ian shape, with the flaps folded and forming ends for the pockets.

3. A s. ring bottom comprising parallel i ri'es of' pockets of substantial y rectan l'ar form, and helical springs of rectangular orm strips 0? material opposite directions toform rectangular re- .ce tacles,. and the incl'osedin said pockets,- eachcasing com rising two strips of fabric of uniform width with overlapping rtions-joi'ned by paralleltmnsverserows o -stitol'iings,.lateral-l margins of the strips .pro'ecting to form fla s, the being alternately folded in ro'ectin fia be' 0 dad and connected wi th the? bodi e s of i 'g ceptaoles thus formed, thereby forming the ends of the receptacles, substantially as and for the purpose set fort 4.
